METAL DOOR.

Application filed January 23, 1914.

T0 all who/m t may concern Be it known that I, ARTHUR L. ABRAHAMS, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Metal Door, of which the following is a specification.

By way of explanation it may be stated that hitherto, much difficulty has been eX- perienccd in the forming of sheet metal doors, by reason of the fact that the constituent sheets of the doors must be manipulated under great pressure, this operation calling for extensive machinery, and making it practically impossible to form a' sheet metal door, saving in an establishment provided with presses and other machines adapted for the specic end above mentioned.

One object of the present invention, therefore, is to provide a door which may be fashionedout of a sheet of metal or other 1eXi-.

ble material, without the use of heavy presses and like expensive machinery, the invention aiming primarily to improve the panel, cross rail and stile portions of the door.

It is within the scope of the invention to improve generally and to enhance the utility of, devices of that type to which the present invention appertains, and to improve processes whereby sheet metal doors are made.

With the above and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made with-v in the scope'of what is claimed without departing from the spirit of the invention.

In the accompanying drawing z-Figure 1 is an elevation of a door constructed in accordance with the present invention, parts being broken away; Fig. 2 is a longitudinal section of the door, parts being broken away; Fig. 3 is a fragmental section on the line 3 3 of Fig. 1; Fig. 4 is a horizontal sectional detail showing the manner in which certain of the cross rails are connected with the stiles; Fig. 5 is a fragmental horizontal sectional detail showing the means whereby one of the constituent sheet or plates of the door is connected with the other sheet along the vertical edges of the door. Fig. 6 is a horizontal sectional detail illustrating a Specification of Letters Patent.

modification of that feature which is depicted in Fig. 5; Fig. 7 is a fragmental vertical section showing a modified means whereby the upper panel of the door is held in place therein; Fig. 8 is a vertical sectional detail illustrating a slight modification in the lower panel of the door.

In carrying out the present invention, the door is shown as comprising two spaced sheets denoted respectively by the numerals 1 and 2, these' sheets being of metal or some other flexible material. The sheet 2 is provided along its vertical edges with rectangular flanges 3 terminating in inwardly projecting feet 4 which are spot-welded or otherwise secured to the sheet 1 as will be understood from Fig. 5. Between the sheets 1 and 2 at the upper end of the door, as Fig. 2 will most clearly show, there is'placed an upright channel 5 which may be spot-welded in position, the channel receiving a filler 6 which may be of wood. Disposed between the sheets 1 and 2 at the lower end of the door is an inverted channel 7 within which is placed a weather strip 8, of felt, rubber or the like, and within the channel 7 and more specifically, within the weather strip 8, is mounted a filler 9 which holds the weather strip in place in the channel, the lower edges of the weather strip projecting beyond the lower edges of the sheets 1 and 2. The channel 7 is spot-welded in place and, without further repetition hereinafter, it will be understood that the spot-welding process may be carried out 'wherever desirable, in connecting the constituent parts of the door, these parts being of metal, saving as specifically modified.

Openings are cut in the sheets 1 and 2, the sheet 2 being bent inwardly so as to form a flange 10 and the sheet 1 being bent inwardly to form an oppositely disposed flange 11,

Vthese flanges 10 and 11 extending around the peripheries of the openings. Located between the sheets 1 and 2 and surrounding the opening through the door, above referred to, is a reinforced member 12 which may be a channel, the channel 12 being folded upon itself to` form an abutment rib 14 which extends between the spaced inner edges of the flanges 10 and 11. The opening above referred to is closed by a.

panel 15 which may be glass. The periphery of the panel may be surrounded by a packing 16 which may be putty, rubber or the like, the panel being held -in. place against lateral movement in one direction by the abutment rib 14. The panel is held n in place against a lateral movement in an opposite direction by means of a bead 17 held in place by screws 18 or other attaching elements which pass through the flange l() and through the channel 12 as shown most clearly in Fig. 2. Below the panel 15, the plates or sheets 1 and 2 are struck inwardly as indicated at 19 to define opposed panels 20 and to form a mid rail 21 and a bottom rail 22. The sheets 1 and 2 are cut at the places where the ends of the rails 21 and 22 merge into the stiles 26, the places of cutting being indicated at 23. Obviously,1 the sheets 1 and 2 are contracted when the panels 20 are formed, and the cutting indicated at 23 permits the sheets to contract and not buckle when the panels are formed. After the panels have been formed, the ends of the cross rails 21 and 22 may be soldered onto the stiles 26 as indicated at 24, and, in addition to the foregoing, the ends ofthe cross rails may be connected with the stiles by strips 25. j In order to permit the necessary contraction of the upper portion of the door when the panels 2O are formed, the sheets 1 and 2 are creased as shown at 28, where the top rail 27 merges into the stiles 26, the creases thus formed being illed with solder as indicated at 29 so as to present a smooth exte-- rior surface, the .detail in question being most readily understood when Fig. 3 is compared with Fig. 1. v

Disposed transversely of the door is a reinforcing element 30 which may be a channel member, the same being united with the bottom'rails 22. Other upright reinforcing ele-` ments 31 may be interposed between and connected with the panels 20. If desired, as shown in Fig. 8, beads 32 may be mounted in place around the peripheries of the panels 20. l

In Fig. 6 there is shown a modified means forl connecting the constituent sheets of the ,door along the vertical edges thereof, the sheets being denotedby t he numeral 33 and being provided with abutting, angularly disposed flanges 34 united by an internal strip 35.

In Fig. 7 there is shown a modified means for holding the upper or removable panel in place.

In Fig. 6 the sheets are indicated at 36 and are provided with inwardly projecting flanges 37 terminating in contacting, projecting abutment ribs 38, this detail replacing the channel member 12 and its rib 14 as shown in Fig. 2. In Fig. 6, the panel is indicated at 39, the packing at 40 and the bead 41, the latter being held in place by means of securing devices 42. The elements 38 may be inclosed in a thin metal channel 38a to keep out the weather.

In constructing a door in accordance with the present invention the sheets 1 and 2 are laid out fiat and cut at all necessary places, such as at 23 and to form the opening in which thelpanel 15 is mounted. The sheets are creased or folded as shown at 28 and the panels 20 are struck in, the contraction resulting from the formation of the panels being cared for by the cutting operations and by the creasing of the material at 28. The strips 25 arc applied, thus vconnecting up the rails 2l and 22 with the Stiles 26, reinforcements and other internal elements are added and the peripheries of the sheets 1 and 2 are joined up as hereinbefore set forth.

Having thus described the invention, what is claimed is A door comprising a sheet of metal, a
